Vapor pressure device

Claim 1

AN APPARATUS FOR AUTOMATICALLY AND CONTINUOUSLY DETERMINING THE VAPOR PRESSURE OF LIQUIDS AND PROVIDING APPROPRIATE RESPONSE TO VARIATIONS THEREIN, THE SAID APPARATUS COMPRISING, IN COMBINATION, A VAPORIZED CHAMBER, A HEATING MEANS FOR SAID CHAMBER AND ASSOCIATED EQUIPMENT, A THERMOSTATIC DEVICE THAT IS DIRECTLY ASSOCIATED WITH THE SAID CHAMBER AND CONTROLS THE HEATING MEANS SO AS TO MAINTAIN THE CHAMBER AT A CONSTANT TEMPERATURE, AN INLET CAPILLARY TUBE CONNECTED AT ONE END TO A SOURCE OF LIQUID AND FORMING AT THE OTHER END AN INLET TO SAID CHAMBER, A SINGLE OUTLET CAPILLARY TUBE OF ADJUSTED LENGTH AND INSIDE DIAMETER THAT IS HEATED BY THE SAID HEATING MEANS AND MAINTAINED THEREBY AT SUBSTANTIALLY CONSTANT TEMPERATURE, AND IS CONNECTED AT ONE END TO THE SAID VAPORIZING CHAMBER TO FORM THE SOLE OUTLET FOR MIXED LIQUIDS AND VAPORS, THE INNER SURFACE OF SAID PASSAGE BEING INTERRUPTED TO PREVENT STREAMLINED FLOW, MEANS FOR INTRODUCING LIQUID INTO THE APPARATUS AT A CONSTANT PRESSURE AND FOR ESTABLISHING A POSITIVE PRESSURE DIFFERENTIAL BETWEEN SAID INLET CAPILLARY AND SAID OUTLET CAPILLARY, AND A PRESSURE GAUGE THAT IS OPERATIVELY ATTACHED TO THE SAID APPARATUS IN SUCH POSITION THAT IT WILL RESPOND TO CHANGES IN BACK PRESSURE THEREIN CREATED BY THE RESISTANCE OF THE SAID OUTLET CAPILLARY TO THE FLOW OF SAID LIQUIDS AND VAPORS.

Claim 2

AN APPARATUS FOR AUTOMATICALLY AND CONTINUOUSLY DETERMINING THE VAPOR PRESSURE OF LIQUIDS AND PROVIDING APPROPRIATE RESPONSE TO VARIATIONS THEREIN, THE SAID APPARATUS COMPRISING, IN COMBINATION, A VAPORIZED CHAMBER, A HEATING MEANS FOR SAID CHAMBER AND ASSOCIATED EQUIPMENT, A THERMOSTATIC DEVICE THAT IS DIRECTLY ASSOCIATED WITH THE SAID CHAMBER AND CONTROLS THE HEATING MEANS SO AS TO MAINTAIN THE CHAMBER AT A CONSTANT TEMPERATURE, AN INLET CAPILLARY TUBE CONNECTED AT ONE END TO A SOURCE OF LIQUID AND FORMING AT THE OTHER END AN INLET TO SAID CHAMBER, A SINGLE OUTLET CAPILLARY TUBE OF ADJUSTED LENGTH AND INSIDE DIAMETER THAT IS HEATED BY THE SAID HEATING MEANS AND MAINTAINED THEREBY AT SUBSTANTIALLY CONSTANT TEMPERATURE, AND IS CONNECTED AT ONE END TO THE SAID VAPORIZING CHAMBER TO FORM THE SOLE OUTLET FOR MIXED LIQUIDS AND VAPORS, THE INNER SURFACE OF SAID PASSAGE BEING INTERRUPTED TO PREVENT STREAMLINED FLOW, MEANS FOR INTRODUCING LIQUID INTO THE APPARATUS AT A CONSTANT PRESSURE AND FOR ESTABLISHING A POSITIVE PRESSURE DIFFERENTIAL BETWEEN SAID INLET CAPILLARY AND SAID OUTLET CAPILLARY, AND A PRESSURE GAUGE THAT IS OPERATIVELY ATTACHED TO THE SAID APPARATUS IN SUCH POSITION THAT IT WILL RESPOND TO CHANGES IN BACK PRESSURE THEREIN CREATED BY THE RESISTANCE OF THE SAID OUTLET CAPILLARY TO THE FLOW OF SAID LIQUIDS AND VAPORS.
